To all whom t may conce/m.'

Be it known that I, Gnoncn BLUMRICK, a

citizen of the United itates, residing at loucester, in the county of'Camden and State of New Jersey, have invented a new and useful Improvement in Gas-Lighting Devices and Methods of Making the Same, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which- Figure l is a perspective view of a section of material from which the gas lighting device is to be formed.

F 2 is a side View of the material illustrated in Fig. l, showing` the manner of stitching.

Fig. 3 is a side view corresponding to Fig.

Fig. a is a side view of one of the gas lighting devices in position on the carrier.

Fig. 5 is a cross sectional view on the line V-V of Fig. 4.

Fig. 6 is a side elevation showing the d'evice applied to a Bunsen tube after it has been burned and shaped, and

Fig. 7 is a plan view of the device shown in Fig. 6.

The present invention has relation to gas lighting devices and is designed to provide an inexpensive, simple and eflicient device of this character adapted to be used as an upright mantle applied to the upper end of a Bunsen burner or the like, for replacing the ordinary bat-wing burners commonly employed.

The object of my invention is to provide a temporary reinforce for upright rag mantles for supporting the delicate ash during and after incineration, prior to the shaping and hardening.

In the preferred form of my invention I form vertical folds in the rag mantle which not only assist in maintaining the rag man tle in an upright position, but also form braces or stays for the delicate ash during and after incineration prior to shaping and hardening.

In one form of my invent-ion the tubular fabric 2, which has been impregnated with refractory salts of rare earth, is folded as indicated at l and 5 in Fig. 1 to form longitudinal reinforcing ribs or folds.

After the material has been folded in the manner described, the upper end thereof is secured in folded position by stitching 6, or the like, extending entirely across the body of the material. without any gathering of the material so that the dark spot ordinarily produced in gas mantles due to the gathering, is obviated.

The opposite corners of the upper end of the stitched material are cut away as indicated more particularly in Fig. 3, to remove the bunched material at the unctions of the folds. By reason of this cutting through the folded material, there are 'formed a plurality of small openings 8 in the stitched end of the device insuring a substantially uniform distribution of the gaseous mixture so that the entire mantle burns at a uniform incandescence. The material constituting the ga lighting device is secured in any desired manner to the carrier T adapted to fit the upper end of a Bunsen burner 9, and provided with an internal gauze. If desired, the upper portion of the mantle may be treated with some suitable material for making the same more inflammable, although such treatment is not essential.

When the device is applied to a Bunsen tube, and the upper portion thereof lighted, it will burn downwardly thereby first burning out the heavier' top portion. During the incineration or burning out of the fabric, the mantle will shrink downwardly and inwardly, and the folds will form stays for the delicate ash. After incineration the gas is turned on and the mantle is lighted, the inrush of gas and air will blow up the mantle to the globular form shown in Fig. 6, while the heat from the burning mixture will harden the mantle.

It will readily be understood by those -familiar with the art, that other temporary supports than those shown and described may be provided for supporting the ash prior to hardening.

The advantages of my invention result from the provision of temporary reinforces for an upright rag mantle which not only form reinforces for the rag mantle, but also form reinforces for the delicate ash prior to the hardening of the mantle.

The provisions of the reinforcing ribs or This stitching takes place folds also facilitate the packaging and shipping of the mantles and sustain the same in an extended position to prevent collapsing.

l. As a new article of manufacture, a tubular limp mantle. for upright Bunsen burners, comprising a body portion folded to form reinforcing ribs, and having the upper end of said body portion stitched in folded condition, sections of said upper end being cut away to form a plurality of gas escape openings, substantially as described.

2. The methodA of making mantles, comprisingiforming a `tulmlar section of material, folding in substantially diametrically opposite sides thereof toform reinforcing ribs, then securing one end of the section of the material in folded condition and removing portions from the opposite sides of said end, substantially as described.

3. The method of making mantles, comprising forming a tubular section of material, folding in substantially diametrically oppositesides thereof to form reinforcing ribs, stitching one end of the section of material in folded condition, removing portionsk from the opposite sides of said end,

and then fastening the opposite end to a carrier, substantially as described.

4. As an article of manufacture, an up'- right rag mantle adapted to shrink downwardly andv inwardly during incineration, said mantle having temporary reinforcing members adapted to form stays for the delicate ash during incineration, substantially as described. v

V5. As an article of manufacture, an upright rag mantle adaptedrto shrink downwardly and inwardly during incineration, said mantle having a series of folds formed therein and adapted to sustain the mantle during incineration by providing stays for the delicate ash, substantially as described.

6. As an' article of manufacture, ain upright rag mantle adapted to Vshrink downlwardly and inwardly during incineration,

Awardly during incineration, said mantle having a series of reinforcing ribs formed therein and adapted to support the mantle during incineration by providing stays for the delicate ash, substantially as described.

8. Asl an article of manufacture, gas lighting device, comprising a carrier, and a rag upright mantle secured thereto and adapted to shrink downwardly and inwardly during incineration, said mantle .having a series of substantially equidistant reinforcing ribs formed therein to support the same during incineration by providing stays for the delicate ash,rsub stantially as described.

In .testimony whereof l have hereunto set my hand.

'GEORGE BLUMRICK.
